Description

Please help!

This have been imaged during good seeing conditions and shortly after a fresh collimation as "quick and dirty" test. Guiding went very well with an RMS guiding error of 0.42 px/s. Some issues occur especially with smaller stars. Post-processing has not been finished. Not clear, why smaler stars are oblong and larger stars not. Will ask this in astrobin forum. Any help is much appreciated.
